Bạn ơi mình nghĩ là phương trình này

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

a,2SO2+O2--->2SO3

b,Al+HCl---->KOH+H2 ( cái này bạn vt sai r)

2Al+6HCl=> 2AlCl3+3H2

c,3Ca+2H3 PO4--->3H2+Ca3 (PO4)2

d,2C6H6+9O2---> 6CO2+6H2O

e,C2H6O+3O2--->2CO2+3H2O

f,  CxHyOz + (x+y/4-z/2) O2 ---> xCO2+ y/2 H2O 

2C_xH_yO_z +\(\frac{4x+y-2z}{2}\) O₂ ===> 2xCO₂ + yH₂O

1. CnH2n+2 + (3n+1)/2O2 ---> nCO2 + (n+1) H2O

2. CnH2n- 2 + (3n-1)/2O2 ---> nCO2 + (n-1) H2O

3.CnH2n-6 + (2n-3)/2O2 ---> nCO2 + (n-3) H2O

4. CnH2n + 3n/2O2 --> nCO2+ nH2O

\(C_nH_{2n-6}+\dfrac{3n-3}{2}O_2\underrightarrow{^{^{t^0}}}nCO_2+\left(n-3\right)H_2O\)

\(C_nH_{2n+2}O+\dfrac{3n}{2}O_2\underrightarrow{^{^{t^0}}}nCO_2+\left(n+1\right)H_2O\)

$1) C_nH_{2n-6} + \dfrac{3n-3}{2}O_2 \xrightarrow{t^o} n CO_2 + (n - 3) H_2O$

$2) C_nH_{2n+2}O + \dfrac{3n}{2}O_2 \xrightarrow{t^o} nCO_2 + (n + 1)H_2O$

\(C_xH_yCOOC_2H_5+\left(\dfrac{2x+y+9}{2}\right)O_2->\left(x+3\right)CO_2+\left(\dfrac{y+5}{2}\right)H_2O\)

\(C_xH_yCOOC_2H_5+\left[\left(3+x\right).2+\dfrac{5+y}{2}-2\right]O_2\underrightarrow{t^o}\left(3+x\right)CO_2\uparrow+\left(\dfrac{5+x}{2}\right)H_2O\)

$C_nH_{2n} + \dfrac{3n}{2}O_2 \xrightarrow{t^o} nCO_2 + nH_2O$
$C_nH_{2n+3}N + \dfrac{3n+1,5}{2}O_2 \xrightarrow{t^o} nCO_2 + (n + 1,5)H_2O + 0,5N_2$

$C_nH_{2n+2}O + \dfrac{3n}{2}O_2 \xrightarrow{t^o} nCO_2 + (n + 1)H_2O$

$Fe + CuSO_4 \to FeSO_4 + Cu$
$4Al(NO_3)_3 \xrightarrow{t^o} 2Al_2O_3 + 12NO_2 + 3O_2$
$3Fe_3O_4 + 8Al \xrightarrow{t^o} 9Fe + 4Al_2O_3$

$3Fe_xO_y + 2yAl \xrightarrow{t^o} yAl_2O_3 + 3xFe$

bạn nào giúp mình với T_T
